Imibuzo Evame Ukubuzwa

Kuyini ukuhlunga okungenamagatsha futhi kungani kubalulekile?

Ukuhlunga okungenamagatsha kususa amagatsha anemibandela (uma/enye izitatimende) emisebenzini yokuqhathanisa, okuvumela ipayipi le-CPU ukuthi lisebenzise ngaphandle kwezijeziso zokungabikezeli kahle. Amaphrosesa anamuhla athembele ekubikezelweni kwegatsha, futhi lapho izibikezelo zihluleka, amapayipi ayayeka. Imiklamo engenamagatsha isebenzisa amaqhinga e-arithmetic afana nokunyakaza okunemibandela ukuze kugcinwe idatha ihamba kahle, okuholela ezikhathini zokuhlunga ngokushesha okukhulu kumasethi wedatha amakhulu noma angaqageleki.

Kushesha kangakanani ukuhlunga okungenagatsha uma kuqhathaniswa nezindlela zendabuko?

Izinzuzo zokusebenza zincike ezicini zedatha, kodwa ukuhlunga okungenagatsha kungase kube ngokushesha okungu-2–5x kokokufaka okungahleliwe noma okuphikisanayo lapho ukubikezela kwegatsha kwehluleka njalo. Kudatha ecishe ihlungwe, inzuzo incipha njengoba ababikezeli bephethe amaphethini kahle. Ukuwina kwangempela kuza ezinhlelweni ezizwelayo ukubambezeleka njengamasistimu esikhathi sangempela, izinjini zegeyimu, nokucutshungulwa kwedatha okuyimvamisa ephezulu lapho i-microsecond ngayinye yokusebenza kahle kwamapayipi kubalwa khona.

Ngingakwazi ukusebenzisa amasu angenagatsha kumaphrojekthi wami?

Nakanjani. Amaphethini angenagatsha asebenza ku-C, C++, Rust, ngisho nezikhathi zokusebenza ze-JavaScript ezithuthukisiwe. Qala ngokushintsha izimo ezilula ufake okulingana ne-arithmetic—ngokwesibonelo, usebenzisa (a > b) * a + (a <= b) * b esikhundleni sokuthi if/else ukuze ubuningi. Onjiniyela abasebenzisa inkundla ye-Mewayz bangahlola amamojula agxile ekusebenzeni kuwo wonke amamojula atholakalayo angu-207, wonke afinyeleleka ngo-$19/mo, ukuze ahlanganise ama-algorithms athuthukisiwe ekugelezeni komsebenzi wokukhiqiza.

Kunini lapho kufanele ngikugweme ukuhlunga okungenagatsha?

Ukuhlunga okungenagatsha akuhlali kuyisinqumo esingcono kakhulu. Kumalungu afanayo amancane (ngaphansi kwama-elementi angu-~64), uhlobo lokufaka olunamagatsha ngokuvamile luyawina ngenxa yokwehla okungaphezulu. Uma idatha ihlungwa kakhulu noma inamaphethini abikezelwayo, izibikezelo zegatsha zithola ukunemba okucishe kufane, okwenza i-overhead engenagatsha ingadingeki. Hlala ulinganisela nedatha yakho yangempela ngaphambi kokuzibophezela endleleni engenagatsha—ukwenza kangcono ngaphambi kwesikhathi ngaphandle kokwenza iphrofayela kungangeza inkimbinkimbi ngaphandle kwenzuzo elinganisekayo.
